At a private meeting held during CeBIT Gigabyte disclosed their upcoming Z87 motherboards. The motherboards start off the the flagship board which is the Z87X-OC, followed by the Z87X-UD5H, Z87X-UD3H and finally the Z87X-D3H. Like most of the socket LGA1150 motherboards being shown this week these boards are still under development. Gigabyte has still yet to finalize the the heatsinks and other features on some of the boards.
As you can guess the Z87X-OC is designed primarily for overclockers. The board features the same black and orange color scheme we have seen on other OC boards from Gigabyte. The board features a 8-phase VRM. You have four DDR3 slots supporting up to 64GB of dual channel memory, three PCI-E 3.0 x16 slots, PCI-E 2.0 x1 slot and two legacy PCI slots. When it comes to connectivity there are six SATA 6GB/s ports, nine USB 3.0 ports, HDMI, DisplayPort, 8-channel HD audio, PS/2 port, and gigabit Ethernet. It also looks like you are going to get all the fly voltage and and frequency controls and dip switches to turn PCI-E lanes off.
The Z87X-UD5H is the first mainstream or power user board in Gigabyte’s Z87 lineup. This board features a 16-phase VRM. You have three PCI-E 3.0 x16 slots, three PCI-E 2.0 x1 slots and a single legacy PCI slot. As far as connectivity there are ten SATA 6GB/s ports, two HDMI ports, dual-link DVI, DisplayPort, 8-channel HD audio, dual gigabit Ethernet and eight USB 3.0 ports (2 header).
The Z87X-UD3H is a more slimmed down version of the Z87X-UD5H. It has an 8-phase VRM. You still have the same expansion slot layout as the UD5H. Connectivity gives you eight SATA 6GB/s ports, and the only other changes are you lose the 2nd Ethernet port for a pair of eSATA ports and the 2nd HDMI port is a VGA port.
At the bottom we have what will be the most affordable board out of the three the Z87X-D3H. It also features an 8-phase VRM. It still keeps the identical expansion slot layout as the other two boards, but it does cut back on SATA and USB 3.0 connectivity. You get a total of six SATA 6GB/s ports and six USB 3.0 ports (2 header).
